[摘要]：In our continuing efforts to identify CGRP receptor antagonists that can be dosed orally for the treatment of migraine headache, we have investigated a pyridine bioisosteric replacement of a polar amide portion of a previous lead compound, BMS-694153. Pyridine derivatives were discovered and their SAR was studied. Some of them showed excellent binding potency. However, oral bioavailability was low, even for compounds with good Caco-2 cell permeability. (C) 2012 Elsevier Ltd. All rights reserved.
